Sending mails from external accounts via that account's server possible?

Sending emails from external accounts works, but it is the Zimbra server that sends them, not the server that holds the external account. Zimbra only sets the 'From:' and 'Reply-To:' fields, but the return path is still the zimbra account and the connection is done from the zimbra server to the dest...

Re: Upgrading from Ubuntu 18.04 to 20.04

Instead of removing /opt/zimbra/jetty_base and using a backup, the better solution is to apt remove zimbra-store package and reinstall it from the downloaded zcs-8.8.15_GA_4179.UBUNTU20_64.20211118033954.tgz! So the complete procedure should be this: 1. On Ubuntu 18.04 - wget https://files.zimbra.c...

Re: memcached amplification attack

Posting again because this needs emphasizing. This is a serious denial-of-service attack! I managed to log in to the router of one of my affected networks but ssh was sooo laaaaaagy. The zimbra server alone (single server setup) was doing 500 Mbit UP! I guess in a multi server zimbra environment you...

Re: memcached amplification attack

This thread should be sticky-ed.
Having to beg the Internet provider late at night to restore the connection at my office for a few minutes so I can add a firewall rule is not fun.

Re: Disk Structure Recommendation

Are you going to install the Open Source Edition or the Network Edition?

What backup strategy are you going to use?

I don't reall...

'Company' phone numbers do not show in Android after CardDAV sync

Other phone numbers, such as 'Mobile' or 'Work' sync without issue, but numbers marked as 'Company' do not get synced to Android address book through CardDAV.

Anyone know a way to fix this, other than changing all numbers from Zimbra address book marked as Company to Work?
